There are two things we need to do before we can start to solve the problem. The first is to remember the equation for the perimeter of a rectangle: P = l+w+l+w or more simply P=2l+2w (where l stands for length and w stands for width) We...

(4 * -10) + (2 * 7) -40+14 -26

7x + 2x + x = 180 (this equation represents that the largest angle is 7 times that of the smallest angle, and the second largest angle is twice the measure of the smallest. we set this equal to 180 because the sum of the angles in a triangle is 180) 10X=180 ...

5x + 3y = 150 (this equation represents the total feet in ribbon used) x + y = 36 (this equation represents the number of ribbons created) Solve by substitution: x=36-y Substitute into first equation: 5(36-y) + 3y = 150 180...

1 |5 -13 4 -6 | 5 -8 -4 5 -8 -4 -10 f(x)=5x^3-13x^2+4x-6; f(1)=-10

Math word problem (answer)

(3*3)+(2*6) 9+12=21

Linear equations (answer)

(6,2) & (0,-1) represent two points on the line defined by the equation: y=1/2x-1 How do we know this is true you ask? Because the solution is given as an ordered pair, we can substitute the values into the equation to see if we end up with a true statement...

Solve for X: Mx + 4y= 3c (answer)

Mx=3c-4y x=(3c-4y)/M

Solve for S: 9s - 5g = -4u (answer)

to solve for s you first have to isolate the term with the s in it. in order to get 9s isolated, I need to get rid of, or move, the 5g. to do this I add 5g to both sides. 9s=-4u+5g I've isolated the term with the s in it, now I have to solve for s by dividing by its coefficient, 9....

The sign rules for multiplying and dividing integers are the same. There are three scenarios: If you are multiplying/dividing two positive integers, your answer will be positive. If you are multiplying/dividing two negative integers, your answer will be positive. If you...
